A mass suspended on a spring will exhibit sinusoidal motion when it moves. If the mass on a spring is 85cm off the ground at its highest position and 41cm off the ground at its lowest position and takes 3.0s to go from the top to the bottom and back again, determine an equation to model the data.

amplitude=8541 divided by 2=22
period=3sec
y=22sin(2pi*t/3)
